 ARTICLE 1 
 DEFINITIONS AND INCORPORATION 
 BY REFERENCE 
 Section 1.01 Definitions. 
 “Acquired Debt” means,
with respect to any specified Person: 
 (1) Indebtedness of any other Person existing at the time such other
Person is merged with or into or became a Subsidiary of such specified Person (regardless of the form of the applicable transaction by which such Person became a Subsidiary) or expressly assumed in connection with the acquisition of assets from any
such Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person or of such Indebtedness being incurred in
connection with the acquisition of assets; and 
 (2) Indebtedness secured by a Lien encumbering any asset

later of the date such Indebtedness is incurred or the date of the related acquisition of assets from such Person. 
 “Additional Notes” means Notes (other than the Initial Notes) issued after the Issue Date in accordance with this Indenture in accordance with Section 2.01 (“Form and Dating”), 2.02 (“Execution and

 “Affiliate” of any specified Person means any other Person directly or indirectly controlling or controlled by or under
direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of
the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise; provided that beneficial ownership of 10% or more of the Voting Stock of a Person will be deemed to be control. For
purposes of this definition, the terms “controlling,” “controlled by” and “under common control with” have correlative meanings. 






 “Agent” means any Registrar, co-registrar, Paying Agent or additional
paying agent. 
 “Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial
interests in any Global Note, the rules and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange. 
 “Asset Sale” means: 
 (1) the sale, lease,
conveyance or other disposition of any assets or rights; provided that the sale, lease, conveyance or other disposition of all or substantially all of the assets of the Parent, the Company and the Restricted Subsidiaries taken as a whole or
the Company and the Restricted Subsidiaries taken as a whole will be governed by the Section 4.18 (“Offer to Repurchase Upon Change of Control”) and/or Section 5.01 (“Merger, Consolidation; Sale of Assets”) hereof, and
not by Section 4.19 (“Asset Sales”) hereof; and 
 (2) the issuance of Equity Interests in any of
the Restricted Subsidiaries or the sale of Equity Interests in any of its Subsidiaries other than statutory or directors qualifying shares. 
 Notwithstanding the preceding, none of the following items will be deemed to be an Asset Sale:

 (6) a Restricted Payment that does not violate Section 4.07 (“Restricted Payments”) hereof or a Permitted

excess thereof. 
 The Company may issue Additional Notes from time to time after the Issue Date, provided such issuance and

Indenture shall govern and be controlling. 
 (b) Global Notes. Notes issued in global form will be substantially in the
form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in certificated form will be substantially in the form of Exhibit A hereto

writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as

benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent
(if other than the Company or a Subsidiary) will have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as
Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

 (5) Neither the Registrar nor the Company will be required: 
 (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15

 If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of
the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company,
an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the (i) the Trustee to protect the Trustee and (ii) the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any
loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. 
  

 38 







 Every replacement Note is an additional obligation of the Company and will be entitled to

Outstanding Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those
canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions of this Indenture, and those described in this Section as not outstanding. Except as
set forth in Section 2.09 (“Treasury Notes”) hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall
not be deemed to be outstanding for purposes of Section 3.07(a) (“Optional Redemption”) hereof. 
 If a Note is
replaced pursuant to Section 2.07 (“Replacement Notes”) hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the principal amount of any Note is considered paid under Section 4.01 (“Payment of Notes”) hereof, it ceases to be
outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of
any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver
or consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so disregarded. 
 Section 2.10 Temporary
Notes. 
 Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt
of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably
acceptable to the Trustee. Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 
  

 39

Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes

replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

 The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal, premium, if any, and interest (without regard to any applicable grace period) from time to time on demand at the rate equal to 2% per annum in excess of the then applicable interest rate on the Notes to the extent lawful to the
Persons who are Holders on a subsequent Record Date, in each case at the rate provided as set forth in the Notes and consistent with Section 4.01 (“Payment of Notes”) hereof (“Default Interest”). The
Company will notify the Trustee in writing of the amount of Default Interest proposed to be paid on each Note and the date of the proposed payment. The Company will fix or cause to be fixed each such Record Date and Interest Payment Date;
provided that no such Record Date may be less than 10 days prior to the related Interest Payment Date. At least 15 days before the Record Date, the Company (or, upon the written request of the Company, the Trustee in the name
and at the expense of the Company) will mail or cause to be sent to Holders a notice that states the Record Date, the related Interest Payment Date and the amount of such interest to be paid. 
 Section 2.13 Persons Deemed Owners. 
 The Holder of a Note may be treated as its owner for all purposes. Only Holders have rights under this Indenture and the Notes. 
 Section 2.14 Interest Payment Date; Record Date. 
 Interest on outstanding Notes will accrue at the rate of 131/2% per
year and will be payable semi-annually in arrears on June 15 and December 15 of each year, commencing on June 15, 2010 (each, an “Interest Payment Date”). The Company will make each interest payment to the Holders of
record on the immediately preceding June 1 and December 1 (each, a “Record Date”). Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently
paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
  

 40 







 Section 2.15 Amortization. 
 The Company will make principal payments of $10.0 million on the Notes (each, an “Amortization Payment”) according to the
following schedule:

	  	$	10.0

 The Company will make each Amortization Payment to the Holders of Records on the
immediately preceding June 1 and December 1 prior to the above scheduled Amortization Payment date (each, a “Amortization Record Date”). Each Amortization Payment will be made on a pro rata basis. Any shortfall in
payment, made necessary by the existence of de minimus dollar amounts that cannot be divided equally among the Holders shall in no way be considered a Default or Event of Default under this Indenture. Such amounts shall be held at DTC and
included in the subsequent Amortization Payment. No change will be made to the face value of the Notes to reflect the Amortization Payments. The Amortization Payments will be reflected in value of the Notes listed on DTC’s records.

notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 10 hereof. 
 The notice will identify the
Notes to be redeemed and will state: 
 (1) the Redemption Date; 
 (2) the redemption price; 
 (3) if the Notes are being redeemed in part: 
 (A) that the Trustee
shall select Notes for redemption on a pro rata basis, by lot or by such other method as the Trustee considers fair and appropriate, unless otherwise required by law or applicable stock exchange or Depositary requirements, and in any case,
not in parts of $2,000 or less; and 
 (B) the portion of the principal amount of such Notes to be redeemed and
that, after the Redemption Date upon surrender of such Notes, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 
 (6) that, unless the Company defaults in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the Redemption Date; 
 (7) the paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and 
  

 42 







 (8) that no representation is made as to the correctness or accuracy of the
CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the Company’s request, the Trustee will give the
notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the Redemption Date, an Officers’ Certificate requesting that the Trustee
give such notice and setting forth the information (or a shorter period as agreed to by the Trustee) to be stated in such notice as provided in this Section above. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of
redemption is sent in accordance with Section 3.03 (“Notice of Redemption”) hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price. A notice of redemption may not be
conditional. 
 Section 3.05 Deposit of Redemption or Purchase Price. 
 No later than 10:00 a.m. Eastern Time on the Redemption Date or Purchase Date, the Company will deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Company any money deposited with the Trustee or
the Paying Agent by the Company in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on, all Notes to be redeemed or purchased. 
 If the Company complies with the provisions of the preceding paragraph, on and after the Redemption Date or Purchase Date, interest will
cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest shall be
paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Company to
comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the Redemption Date or Purchase Date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at
the rate provided in the Notes and in Section 4.01 (“Payment of Notes”) hereof. 
 Section 3.06 Notes Redeemed or
Purchased in Part. 
 Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon
receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

 Section 3.08 Optional Redemption for Changes in Withholding Taxes 
 (a)
At any time, the Company may redeem all, but not less than all, of the Notes, on not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the
applicable Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date), in the event that the Company or the Guarantors, as the case may be, has become or
would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of a change in or an amendment to the laws (including any regulations or rulings promulgated
thereunder) of any Specified Tax Jurisdiction (or any relevant jurisdiction, political subdivision or taxing authority thereof or therein), or any change in or amendment to any official position regarding the application or interpretation of such
laws, regulations or rulings (including a holding by a court of competent jurisdiction), which change or amendment is announced or becomes effective on or after the date of this Indenture, and the Company or the Guarantors, as the case may be,
cannot avoid such obligation by taking reasonable measures available to them; provided that the Board of Directors of the Parent determines in good faith that the aggregate amount of such Additional Amounts would create additional annual costs in
excess of 0.50% of the aggregate principal amount of Notes then outstanding; and 
 (A) no such notice of
redemption shall be given earlier than 60 days prior to the earliest date on which the Company or the Guarantors, as the case may be, would be obligated to pay such Additional Amounts if a payment in respect of the Notes or the Note Guarantee were
then due, and 
  

 44 







 (B) at the time any such redemption notice is given, such obligation to pay
Additional Amounts must remain in effect. 
 Prior to any redemption of the Notes, the Company will be required to deliver to
the Trustee (i) an Officers’ Certificate stating that (x) the Company or the Guarantors, as the case may be, cannot avoid obligations to pay Additional Amounts by taking reasonable measures available to them and (y) the Company
is otherwise entitled to effect such redemption and attaching the resolutions of the Board of Directors of the Parent as to additional annual costs described above and (ii) an opinion of independent legal counsel of recognized standing stating
that the Company would be obligated to pay Additional Amounts as a result of a change in tax laws or regulations and, in the case of (i) and (ii), stating that the conditions precedent to the right of redemption have occurred. No such notice of
redemption may be given more than 60 days before or more than 270 days after the Company or any Guarantors, as the case may be, first becomes liable or aware of the liability to pay any Additional Amounts as a result of a change or amendment
described above. 
 (b) Any redemption pursuant to this Section shall be made pursuant to the provisions of Sections 3.01
(“Notices to Trustee”) through 3.06 (“Notes Redeemed or Purchased in Part”) hereof. 
 Section 3.09 Special

Topaz Driller designated as “Topaz Driller construction payment” as described under “Use of Proceeds” in the Offering Memorandum into an escrow account to be established by Wilmington Trust FSB, as escrow agent,
pursuant to an escrow agreement (the “Topaz Escrow Agreement”), pursuant to which the escrowed amount shall be released to the Company to satisfy the final construction payment for the Topaz Driller as described in the
Offering Memorandum, upon written request. If, within 90 days of the Issue Date, (i) the Company has not accepted the Topaz Driller, (ii) clean title for the Topaz Driller is not transferred to the Company, (iii) the
Topaz Driller is not registered in the name of the Company as owner under Panamanian flag and (iv) a Ship Mortgage is not recorded on the Topaz Driller in favor of the Noteholder Collateral Agent, each as certified to the Trustee
in an Officers’ Certificate, then the Company shall be required to redeem the Notes issued under this Indenture upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount thereof, plus
accrued and unpaid interest on the Notes redeemed to the applicable Redemption Date.

 In the event that, pursuant to Section 4.19 (“Asset Sales”) hereof, the Company shall be required to commence an “Asset Sale Offer”, it will follow the procedures specified below
and in Sections 4.19(c), (d), (e) and (f) (“Asset Sales”): 
 (a) The Asset Sale Offer shall be made to all
Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. 

 

 45 







 (b) The Asset Sale Offer will remain open for a period of at least 20 Business Days
following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). 
 (c) No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Company will
apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and
other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
 (d) If the Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at
the close of business on such Record Date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer. 
 (e) Upon the commencement of an Asset Sale Offer, the Company will send, by first class mail, a notice to the Trustee and each of the Holders. The notice will contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state: 
 (1) that the Asset Sale Offer is being made pursuant to this Section 3.10 and Section 4.19 (“Asset
Sales”) hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer Amount, the
purchase price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to
accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Note accepted for payment
pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date; 
 (5) that Holders
electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in amounts not less than $2,000 and, thereafter, in integral multiples of $1,000 only; 
 (6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note,
with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the
notice at least three days before the Purchase Date; 
  

 46 







 (7) that Holders will be entitled to withdraw their election if the Paying
Agent receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased; 
 (8) that, if the aggregate principal amount of
Notes and other pari passu Indebtedness surrendered by Holders thereof exceeds the Offer Amount, the Trustee will select the Notes and the Company will select other pari passu Indebtedness to be purchased on a pro rata basis
based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that no Note of $2,000 or less can be redeemed in part and that minimum
denominations of $1,000 in excess thereof are maintained); and 
 (9) that Holders whose Notes were purchased
only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
 On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered
pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that
such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.10 and Section 4.19 (“Asset Sales”). The Company, the Depositary or the Paying Agent, as the case may
be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and
the Company will promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the
Purchase Date. 
 (f) Other than as specifically provided in this Section 3.10, any redemption pursuant to this
Section 3.10 shall be made pursuant to the provisions of Sections 3.01 (“Notices to Trustee”) through 3.06 (“Notes Redeemed or Purchased in Part”) hereof. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder
to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sales provisions of
this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.10 and Section 4.19 (“Asset Sales”) of this Indenture by
virtue of such conflict.

 (2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; 
 provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or
other existence of any of its Subsidiaries, if the Board

  

 48 







 
of Directors of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the
loss thereof would not have a material adverse effect on the Company and its Subsidiaries, taken as a whole.

of the signing Officers with a view to determining whether the Company has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that to the best of his
or her actual knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this

 Section 4.06 Stay, Extension and Usury Laws. 
 The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or

lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit

the Stated Maturity thereof; or 
 (4) make any Restricted Investment 
 (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted

 unless, at the time of and after giving effect to such Restricted Payment: 
 (1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment;

 (2) the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if

 (A) 50% of the Consolidated Net Income of the Company and any Guarantors on a combined or consolidated basis, as the case may be (meaning the Parent is included but the Excluded Parent Subsidiaries are
not included in that combination or consolidation), for the period (taken as one accounting period) from the first day of the first fiscal quarter commencing after the date of this Indenture to the end of the Company’s most recently ended
fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit); plus 
  

 50 







 (B) 100% of the aggregate net cash proceeds received by the Company since
the date of this Indenture as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or
convertible or exchangeable debt securities of the Company that have been converted into or exchanged for such Equity Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company), provided,
however, that the Parent Advance shall not constitute net cash proceeds contemplated by this paragraph (b); plus 
 (C) to the extent that any Restricted Investment that was made after the date of this Indenture is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted

 (D) to the extent that any Unrestricted Subsidiary designated as such after the date of this Indenture is redesignated as a Restricted Subsidiary after the date of this Indenture, the lesser of
(i) the Fair Market Value of the Parent’s or the Company’s Investment in such Subsidiary, as the case may be, as of the date of such redesignation or (ii) such Fair Market Value as of the date on which such Subsidiary was
originally designated as an Unrestricted Subsidiary after the date of this Indenture; plus 
 (E) 50% of
any dividends received by the Company or a Restricted Subsidiary after the date of this Indenture from an Unrestricted Subsidiary, to the extent that such dividends were not otherwise included in the Consolidated Net Income of the Company for such
period. 
 (b) So long as no Default has occurred and is continuing or would be caused thereby, the preceding provisions will
not prohibit: 
 (1) the payment of any dividend or distribution or the consummation of any irrevocable
redemption within 60 days after the date of declaration of the dividend or

  

 51 







 
distribution or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend, distribution or redemption payment would have complied with the
provisions of this Indenture; 
 (2) the making of any Restricted Payment in exchange for, or out of the net cash
proceeds of the substantially concurrent sale (other than to a Subsidiary of the Company) of, Equity Interests of the Company (other than Disqualified Stock) or from the substantially concurrent contribution of common equity capital to the Company;
provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded from clause (3)(B) of the preceding paragraph; 
 (3) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of the Company or any
Guarantor that is contractually subordinated to the Notes or to any Note Guarantee with the net cash proceeds from a substantially concurrent incurrence of Permitted Refinancing Indebtedness; 
 (4) the payment of any dividend (or, in the case of any partnership or limited liability company, any similar distribution)
by a Restricted Subsidiary to the holders of its Equity Interests on a pro rata basis; 
 (5) the
declaration and payment of regularly scheduled or accrued dividends to holders of any class or series of Disqualified Stock of the Company or any Restricted Subsidiary issued after the date of this Indenture in accordance with the Consolidated
Interest Coverage Ratio set forth in Section 4.08(a)(2) (“Incurrence of Indebtedness and Issuance of Preferred Stock”); 
 (6) the repurchase of Capital Stock deemed to occur upon the exercise of options or warrants to the extent that such Capital Stock represents all or a portion of the exercise price thereof; 
 (7) Permitted Parent Payments; and 
 (8) the dividend or distribution by the Company to the Parent any time after six months after the Issue Date of $9.1 million
(representing the first interest payment advanced by the Parent to the Company as set forth under Section 4.22 (“Parent Advance”)). 
 (c) The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the
Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair Market Value of any assets or securities that are required to be valued by this Section will be determined by the Board of Directors of the
Parent whose resolution with respect thereto will be delivered to the Trustee. The Board of Directors’ determination must be based upon an opinion or appraisal issued by an accounting, appraisal or investment banking firm of national standing
if the Fair Market Value exceeds $10.0 million.

create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), none of the Parent, the
Company or any Guarantor will issue any Disqualified Stock and the Parent will not permit the Company or any of the Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that: 
 (1) the Parent may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Consolidated Interest
Coverage Ratio of the Parent and its Subsidiaries on a consolidated basis, for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock is issued, as the case may be, would have been at least 1.75 to 1; or 
 (2) the Company or Guarantor (other than the Parent) may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock, if the Consolidated Interest Coverage Ratio for the Company, together
with any Restricted Subsidiaries on a combined or consolidated basis, as the case may be, for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred or such Disqualified Stock is issued, as the case may be, would have been at least 3.0 to 1, 
 in each case determined on a pro forma basis (including a pro forma application of the Net Proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock had been issued, as the case may be,
on the first day of such four-quarter period. 
 (b) The provisions of Section 4.08(a) (“Incurrence of Indebtedness
and Issuance of Preferred Stock”) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”): 
 (1) (A) the incurrence by the Company or any Guarantor (other than the Parent) of letters of credit under an LC Facility in
an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company or any Guarantor, as applicable, thereunder)
not to exceed $5.0 million; and (B) the incurrence by the Parent of letters of credit under an LC Facility in connection with the bidding for certain contracts in the ordinary course (including in connection with bid bonds, performance bonds
and similar instruments) in any aggregate principal amount at any one time outstanding under this clause (1)(B) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Parent thereunder)
not to exceed $15.0 million; 
 (2) the incurrence by the Company and any Guarantor of Indebtedness represented
by the Notes and the related Note Guarantees to be issued on the Issue Date; 
  

 53 







 (3) the incurrence by the Company or any Guarantor of Indebtedness
represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of
property, plant or equipment used in the business of the Company or any of the Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or
discharge any Indebtedness incurred pursuant to this clause (3), not to exceed $2.0 million at any time outstanding; 
 (4) Indebtedness of the Company or any Guarantor incurred and outstanding on or prior to the date on which a new Subsidiary was acquired by the Company or such Guarantor (other than Indebtedness incurred in contemplation of, or in
connection with, the transaction or series of related transactions pursuant to which such Subsidiary became a Subsidiary of or was otherwise acquired by the Company or such Guarantor); provided, however, that (a) on the date that such
Subsidiary is acquired by, or is merged into the Company or such Guarantor, as the case may be, would have been able to incur $1.00 of additional Indebtedness pursuant to clause (a)(1) or (b)(2), as the case may be, of this Section 4.08(a)
after giving effect to the incurrence of such Indebtedness pursuant to this clause (4); and (b) the new Subsidiary becomes a Restricted Subsidiary and a Guarantor; 
 (5) the incurrence by the Company or any Guarantors of Permitted Refinancing Indebtedness in exchange for, or the Net
Proceeds of which are used to renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under the first paragraph of this Section or clauses
(2) or (5) of this paragraph; 
 (6) the incurrence by the Company or any Guarantor of intercompany
Indebtedness between or among the Company and the Guarantors; provided, however, that: 
 (A) if the
Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes
and the Note Guarantees; and 
 (B) any (i) subsequent issuance or transfer of Equity Interests that results
in any such Indebtedness being held by a Person other than the Company or a Guarantor, or (ii) sale or other transfer of any such Indebtedness to a Person that is not the Company or a Guarantor, 
 will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Guarantor, as the case may be, that was not permitted
by this clause (6); 
 (7) the incurrence by the Company or any Guarantor of Hedging Obligations in the ordinary
course of business; 
  

 54 







 (8) the guarantee by the Company or any Guarantor of Indebtedness of the
Company or a Guarantor that was permitted to be incurred by another provision of this Section 4.08; provided that if the Indebtedness being guaranteed is subordinated to or pari passu with the Notes, then the Guarantee shall be
subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (9) the
incurrence by the Company or any Guarantor of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, and performance and surety bonds in the ordinary course of business; 
 (10) the incurrence by the Company or any Guarantor of Indebtedness arising from the honoring by a bank or other financial
institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; and 
 (11) the Incurrence by the Company or any Guarantor of Indebtedness arising from agreements providing for indemnification,
adjustment of purchase price or similar obligations, or Guarantees or letters of credit, surety bonds or performance bonds securing any obligations of the Parent or any of the Guarantors pursuant to such agreements, in any case incurred in
connection with the disposition of any business, assets or Guarantor (other than Note Guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Restricted Subsidiary for the purpose of financing such
acquisition), so long as the amount does not exceed the gross proceeds actually received by Parent or any Guarantor in connection with such disposition. 
 None of the Company or any Guarantor will incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such
Guarantor unless such Indebtedness is also contractually subordinated in right of payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be
contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured or by virtue of being secured on a junior Lien basis. 
 For purposes of determining compliance with this Section 4.08, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in
clauses (1) through (11) above, or is entitled to be incurred pursuant to paragraph (a) of this Section 4.08, the Company, the applicable Restricted Subsidiary or the applicable Guarantor will be permitted to classify such item
of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.08. The accrual of interest, the accretion or amortization of original issue
discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on
Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.08; provided, in each
such case, that the amount of any such accrual, accretion or payment is included in Consolidated

  

 55 







 
Interest Expense of the Company as accrued. Notwithstanding any other provision of this Section 4.08, the maximum amount of Indebtedness that the Company, the applicable Restricted
Subsidiary or the applicable Guarantor may incur pursuant to this Section shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 The amount of any Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 

(2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

 (A) the Fair Market Value of such assets at the date of determination; and 
 (B) the amount of the Indebtedness of the other Person. 
 Section 4.09 Liens. 
 Neither the Parent nor the Company will, and
neither of them will permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any asset now owned or hereafter acquired, except Permitted Liens. 
 Section 4.10 Dividend and Other Payment Restrictions Affecting Subsidiaries. 
 Neither the Parent nor the Company will, and neither of them will permit any Restricted Subsidiaries to, directly or indirectly, create or
permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital Stock to the Company or any Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its
profits, or pay any Indebtedness owed to the Company or any Restricted Subsidiaries; 
 (2) make loans or
advances to the Company or any Restricted Subsidiaries; or 
 (3) sell, lease or transfer any of its properties
or assets to the Company or any Restricted Subsidiaries. 
 However, the preceding restrictions will not apply to encumbrances
or restrictions existing under or by reason of: 
 (1) any future LC Facility, provided that the encumbrances and
restrictions contained therein, including any related collateral documents, and any amendments,

  

 56 







 
restatements, modifications, renewals, supplements, refundings, replacements or refinancings thereof are not materially more restrictive, taken as a whole, with respect to such dividend and other
payment restrictions than those contained in this Indenture; 
 (2) agreements governing Existing Indebtedness as
in effect on the date of this Indenture and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals,
supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of this Indenture;

 (3) this Indenture, the Notes and Note Guarantees; 
 (4) applicable law, rule, regulation or order; 
 (5) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any Restricted Subsidiaries
as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the
properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred; 

(6) customary non-assignment provisions in contracts and licenses entered into in the ordinary course of business;

 (7) purchase money obligations for property acquired in the ordinary course of business, mortgage financings
and Capital Lease Obligations that impose restrictions on the property purchased or mortgaged or leased of the nature described in clause (3) of the preceding paragraph; 
 (8) any agreement for the sale or other disposition of any Restricted Subsidiary that restricts distributions by that
Restricted Subsidiary pending the sale or other disposition; 
 (9) Permitted Refinancing Indebtedness;
provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being
refinanced; 
 (10) Liens permitted to be incurred under Section 4.09 (“Liens”) that limit the
right of the debtor to dispose of the assets subject to such Liens; 
 (11) provisions limiting the disposition
or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements, which limitation is applicable only to the assets that are the subject of such
agreements; 
  

 57 







 (12) restrictions on cash or other deposits or net worth imposed by
customers under contracts entered into in the ordinary course of business; and 
 (13) restrictions contained in,
or in request of, Hedging Obligations permitted to be incurred by this Indenture. 
 Section 4.11 Transactions with Affiliates.

 (a) The Company will not, and will not permit any Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company and any Restricted Subsidiary (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with
an unrelated Person; and 
 (2) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration
in excess of $5.0 million, a resolution of the Board of Directors of the Parent set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11 and that such Affiliate Transaction has been
approved by a majority of the disinterested members of the Board of Directors of the Parent; and 
 (B) with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $15.0 million, an opinion as to the fairness to the Company or such Restricted Subsidiary of such Affiliate Transaction
from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
 (b) The
following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph: 
 (1) transactions between or among the Company and/or any Restricted Subsidiaries; 
 (2) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest
in, or controls, such Person; 
  

 58 







 (3) Restricted Payments that do not violate Section 4.07
(“Restricted Payments”); 
 (4) any agreement as in effect on the date of the issuance of the Notes or
any amendments, renewals or extensions of any such agreement (so long as such amendments, renewals or extensions are not less favorable to the Holders); 
 (5) the entering into of a customary agreement providing registration rights to the shareholders of Parent and the performance of such agreements; and 
 (6) transactions between or among the Parent and any of its Subsidiaries (including transactions between or among the
Company, any Guarantor or any Restricted Subsidiary), on the one hand, and any Excluded Parent Subsidiary, on the other hand, provided that such transaction is entered into in the ordinary course of business and on an arm’s length basis and
that any such transaction is approved by a majority of the Parent’s disinterested directors. 
 Section 4.12 Business
Activities. 
 Neither the Parent nor the Company will not, and will not permit any Restricted Subsidiaries to, engage in any
business other than Permitted Businesses, except to such extent as would not be material to the Company and any Restricted Subsidiaries taken as a whole. 
 Section 4.13 Credit Rating for the Notes. 
 The Company and the Parent
shall obtain within 365 days from the date of this Indenture a credit rating for the Notes from Moody’s and S&P and shall maintain a credit rating for the Notes with Moody’s and S&P until all of the Obligations of the Company under
this Indenture have been satisfied or discharged under the terms of this Indenture. If either Moody’s or S&P ceases to rate the Notes for reasons outside of the control of the Company, the Company and the Parent shall obtain a credit rating
from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Company as a replacement agency. 
 Section 4.14 Additional Note Guarantees. 
 If (a) the Company or any Restricted Subsidiaries acquires or creates another Subsidiary, (b) the Parent acquires or creates another Subsidiary to directly or indirectly own the Equity Interest
of the Company or any Restricted Subsidiary or (c) any Subsidiary of the Parent or the Company that is not already a Guarantor is the subject of a Contract Winning Trigger, after the Issue Date, then the Parent and the Company will 

(1) cause that Subsidiary to 
 (A) execute a supplemental indenture pursuant to which it will become a Guarantor, 
  

 59 







 (B) execute an amendment to the Collateral Agreements pursuant to which it
becomes subject to the obligations of a Guarantor thereunder and pledge its assets, including the Equity Interests it owns in any of its Subsidiaries, pursuant to the Collateral Agreements; 
 and 
 (2) deliver an Opinion of Counsel reasonably satisfactory in form to the Trustee, in each case within 20 Business Days of the date on which the Subsidiary was acquired or created or otherwise becomes
subject to this Section; provided that 
 (A) any Subsidiary that constitutes an Immaterial Subsidiary
need not become a Guarantor until such time as it ceases to be an Immaterial Subsidiary; and 
 (B) any
applicable Subsidiary may be released from its Note Guarantee and related pledge following the occurrence of a Contract Unwind Trigger provided the conditions to that release are satisfied. 
 Section 4.15 Designation of Restricted and Unrestricted Subsidiaries. 
 (a) The Board of Directors of the Parent may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if: 
 (1) the Company could make the Restricted Payment which is deemed to occur upon such designation in accordance with
Section 4.07 (“Restricted Payments”) equal to the appropriate Fair Market Value of all outstanding Investments owned by the Parent, the Company or the Restricted Subsidiaries in such Subsidiary at the time of such designation;

 (2) such Restricted Subsidiary meets the definition of an “Unrestricted Subsidiary”; 
 (3) the designation would not constitute or cause (with or without the passage of time) a Default or Event of Default or no
Default or Event of Default would be in existence following such designation; and 
 (4) the Company delivers to
the Trustee a certified copy of a resolution of the Board of Directors of the Parent giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by
Section 4.07 (“Restricted Payments”). 
 If a Restricted Subsidiary is designated as an Unrestricted Subsidiary,
the aggregate Fair Market Value of all outstanding Investments owned by the Parent, the Company or the Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the
designation and will reduce the amount available for Restricted Payments under Section 4.07 (“Restricted Payments”) or under one or more clauses of the definition of Permitted Investments, as determined by the Company. 
  

 60 







 If, at any time, any Unrestricted Subsidiary designated as such would fail to meet the
preceding requirements as an Unrestricted Subsidiary or any other Unrestricted Subsidiary would fail to meet the definition of an “Unrestricted Subsidiary,” then such Subsidiary will thereafter cease to be an Unrestricted Subsidiary for
purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.08
(“Incurrence of Indebtedness and Issuance of Preferred Stock”), the Company or the applicable Guarantor will be in default of such covenant. 
 In connection with the occurrence of a Contract Unwind Trigger, the Parent or the Company may cause an applicable Subsidiary to be designated an Unrestricted Subsidiary if it meets the conditions set
forth in clause (a) of this Section 4.15. 
 (b) The Board of Directors of the Parent may at any time designate any
Unrestricted Subsidiary or Subsidiary of the Parent to be a Restricted Subsidiary if: 
 (1) the Company and the
Guarantor could incur the Indebtedness which is deemed to be incurred upon such designation under Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”), equal to the total Indebtedness of such Subsidiary
calculated on a pro forma basis as if such designation had occurred on the first day of the four-quarter reference period; 
 (2) the designation would not constitute or cause a Default or Event of Default; and 
 (3) the Company delivers to the Trustee a certified copy of a resolution of the Board of Directors of the Parent giving effect to such designation and an Officers’ Certificate certifying that such
designation complied with the preceding conditions, including the incurrence of Indebtedness under Section 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”). 
 The Parent or the Company shall be required to designate each applicable Subsidiary to become a Restricted Subsidiary and a Guarantor and
pledge its assets and property as Collateral pursuant to Section 4.14 (“Additional Note Guarantees”), upon the occurrence of a Contract Winning Trigger and shall be required to comply with the conditions set forth in this clause
(b) of this Section 4.15 in connection therewith. For the avoidance of doubt, any direct or indirect Subsidiary of the Parent may become a Restricted Subsidiary for purposes of this Indenture notwithstanding the fact that such Subsidiary
is a Subsidiary of the Parent but not the Company. 
 Section 4.16 Payments for Consent. 
 The Company will not, and will not permit any Restricted Subsidiaries and their Affiliates to, directly or indirectly, pay or cause to be
paid any consideration to or for the benefit of any Holder for or as an inducement to any consent, waiver or amendment of any of the terms

  

 61 







 
or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set
forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.17 Reports. 
 (a) Whether or not required by the rules and regulations of the SEC, so long as any Notes are outstanding, the Parent or the Company will
furnish to the Holders or cause the Trustee to furnish to the Holders of Global Notes, within the time periods specified in the SEC’s rules and regulations: 
 (1) all quarterly reports on Form 10-Q and annual reports on Form 10-K that would be required to be filed with the SEC on
such forms if the Parent or the Company were required to file such reports under the Exchange Act; 
 (2) all
current reports on Form 8-K that would be required to be filed with the SEC on such form if the Parent or the Company were required to file such reports under the Exchange Act; and 
 (3) in a footnote to the Parent’s financial statements included in quarterly or annual reports to be filed or furnished
pursuant to clauses (1) and (2) of this Section 4.17(a), the financial information required to comply with Rule 3-10 of Regulation S-X under the Securities Act. 
 All such reports will be prepared in all material respects in accordance with all of the rules and regulations applicable to such reports.
Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Parent’s or the Company’s certified independent accountants. In addition, the Parent will post the reports on its website
within the time periods specified in the rules and regulations applicable to such reports and the Parent will file a copy of each of the reports referred to in clauses (1) and (2) of this Section 4.17(a) with the SEC for public
availability within those time periods (unless the SEC will not accept such a filing). The Parent will be deemed to have delivered or filed such reports with the Trustee and Holders if the Parent has filed such reports with the SEC via the EDGAR
filing system. 
 If at any time the Parent is no longer subject to the periodic reporting requirements of the Exchange Act for
any reason, the Parent or the Company will nevertheless continue filing the reports specified in the preceding paragraphs of this Section 4.17(a) with the SEC within the time periods specified by the SEC for registrants that are non-accelerated
filers unless the SEC will not accept such a filing. Neither the Parent nor the Company will take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the
Parent’s or the Company filings for any reason, the Parent or the Company will post the reports referred to in the preceding paragraphs on its website within the time periods that would apply to non-accelerated filers if the Parent or the
Company were required to file those reports with the SEC. 
 (b) The quarterly and annual reports and financial information
required by the preceding paragraphs will include a Management’s Discussion and Analysis of Financial

  

 62 







 
Condition and Results of Operations (the “MD&A”) of the Parent, which shall include a discussion and analysis of the Company and any Restricted Subsidiaries. If the Company has
designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraphs will include a reasonably detailed presentation, either on the face of the financial statements
or in the footnotes thereto, and also in the MD&A, of the financial condition and results of operations of the Company and the Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted
Subsidiaries. 
 The Parent will hold a quarterly conference call for the Holders and securities analysts to discuss such
financial information no later than ten Business Days after distribution of such financial information. 
 (c) In addition, the
Company and Guarantors agree that, for so long as any Notes remain outstanding, if at any time they are not required to file with the SEC the reports required by the preceding paragraphs, they will furnish to the Holders and to securities analysts
and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 Section 4.18 Offer to Repurchase Upon Change of Control. 
 (a) If a Change of Control occurs, each Holder
will have the right to require the Company to repurchase all or any part (equal to a minimum amount of $2,000 and integral multiples of $1,000) of that Holder’s Notes pursuant to a change of control offer (a “Change of Control
Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer a payment (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within ten Business Days
following any Change of Control, the Company will mail a notice to the Trustee and each Holder describing the transaction or transactions that constitute the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this Section 4.18 and that all Notes tendered will be
accepted for payment; 
 (2) the purchase price and the purchase date, which shall be no earlier than 30 days and
no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 
 (3) that any Note not tendered will continue to accrue interest; 
 (4) that, unless the Company
defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the
Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry

  

 63 







 
transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of
business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that
such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are
being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount and integral multiples of $1,000. 

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the
provisions of this Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations pursuant to the provisions of this Indenture by virtue of such compliance. 

(b) On or before the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 

(2) by 10:00 a.m. Eastern Time on the Change in Control Payment Date, deposit with the Paying Agent an amount equal to the
Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (3) deliver or
cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying Agent will promptly send to each Holder properly tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount
of $2,000 or in integral multiples of $1,000 in excess thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 The provisions described above that require the Company to make a Change of Control Offer following a Change of Control will be applicable
whether or not any other provisions of this Indenture are applicable. 
  

 64 







 The Company will not be required to make a Change of Control Offer upon a Change of Control
if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes
properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to this Indenture as described above under Article 3 unless and until there is a default in payment of the applicable
redemption price. 
 Section 4.19 Asset Sales. 
 (a) The Company will not, and will not permit any Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company or the Restricted Subsidiary, as the case may be, receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or
sold or otherwise disposed of; and 
 (2) at least 75% of the consideration received in the Asset Sale by the
Company or such Restricted Subsidiary is in the form of cash; provided, however, to the extent that any disposition in such Asset Sale was of Collateral, the non-cash consideration received is pledged as Collateral under the Collateral
Agreements simultaneously with such sale, in accordance with the requirements set forth in this Indenture. 
 For purposes of
this Section 4.19, each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the
Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the
transferee of any such assets so long as the Company or such Restricted Subsidiary are released from further liability; 
 (B) any securities, Notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are contemporaneously, subject to ordinary settlement periods, converted by the Company or such Restricted
Subsidiary into cash, to the extent of the cash received in that conversion; and 
 (C) any stock or assets of
the kind referred to in clauses (2) or (4) of paragraph (b) of this Section 4.19. 
 (b) Within 360 days
after the receipt of any Net Proceeds from an Asset Sale, the Company or the applicable Restricted Subsidiary, as the case may be, may apply such Net Proceeds: 
 (1) to repay or purchase Notes; 
  

 65 







 (2) to acquire all or substantially all of the assets of, or any Capital
Stock of, another Permitted Business of the Company, if, after giving effect to any such acquisition of Capital Stock, such Permitted Business is or becomes a Restricted Subsidiary; 
 (3) to make a capital expenditure for the Company or any of its Restricted Subsidiaries; or 
 (4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in the
Company’s Permitted Business. 
 Pending the final application of any Net Proceeds, the Company may invest the Net Proceeds
in the Company and the Restricted Subsidiaries in any manner that is not prohibited by this Indenture and the Collateral Agreements; provided that pending any such application, the proceeds of the Asset Sale, whether assets, property or cash,
are subject to the Lien of the Collateral Agreements. 
 (c) Any Net Proceeds from Asset Sales that are not applied or invested
as provided in paragraph (b) of this Section 4.19 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will, within five Business Days thereof, make an offer
(the “Asset Sale Offer”) to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. 
 (d) The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of
purchase, and will be payable in cash. 
 (e) If any Excess Proceeds remain after consummation of an Asset Sale Offer, the
Company may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture and the Collateral Agreements; provided that pending any such application, the proceeds of the Asset Sale, whether assets, property or cash, are
subject to a Lien under the Collateral Agreements. 
 (f) If the aggregate principal amount of Notes and other pari passu
Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes and the Company shall select such other pari passu Indebtedness to be purchased on a pro rata basis, provided
that applicable denominations of the Notes are preserved. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 The Company will not and will not permit any Restricted Subsidiary to, enter into or suffer to exist any agreement that would place any restriction of any kind (other than pursuant to law or regulation)
on the ability of the Company to make an Asset Sale Offer. 
 The Company will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To

  

 66 







 
the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance. 
 Section 4.20 Impairment of Security Interest. 
 Neither the Company nor any of its Restricted Subsidiaries
will take or omit to take any action which would adversely affect or impair in any material respect the Liens in favor of the Noteholder Collateral Agent with respect to the Collateral, except as otherwise permitted or required by the Collateral
Agreements or this Indenture. Neither the Company nor any of its Restricted Subsidiaries will enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or
retire any Indebtedness of any Person, other than as permitted by this Indenture and the Collateral Agreements. 
 The Company
shall, and it shall cause each Guarantor to, at its sole cost and expense, execute and deliver all such agreements and instruments and take all further action as the Noteholder Collateral Agent or the Trustee shall reasonably request to more fully
or accurately describe the property intended to be Collateral or the obligations intended to be secured by the Collateral Agreements. The Company shall, and it shall cause each Guarantor to, at its sole cost and expense, file any such notice filings
or other agreements or instruments as may be reasonably necessary or desirable under applicable law to perfect the Liens created by the Collateral Agreements. 
 Any release of Collateral in accordance with Section 12.03 (“Release of Collateral”), and the Collateral Agreements will not be deemed to impair the security under this Indenture, and any
appraiser or other expert may rely on such provision in delivering a certificate requesting release so long as all other provisions of this Indenture with respect to such release have been complied with. 
 Section 4.21 Withholding Taxes 
 (a) All payments made on behalf of the Company or any Guarantor under or with respect to the Notes or the Note Guarantee must be made free and clear of and without withholding or deduction for, or on account of, any present or future tax,
duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of any Specified Tax Jurisdiction or by any authority or agency therein or thereof
having power to tax (or the jurisdiction of incorporation of any successor of the Company or the Guarantors) (hereinafter “Taxes”), unless the Company or the applicable Guarantor, as applicable, are so required to withhold or deduct
Taxes by law or by the interpretation or administration thereof by the relevant government authority or agency. 
 (b) If the
Company or any Guarantor (or any successor of any of them), as applicable, are so required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes or the Note Guarantee, the Company or
such Guarantor (or any successor of any of them), as applicable, will be required to pay such additional amounts

  

 67 







 
(“Additional Amounts”) as may be necessary so that the net amount received by each Holder (including Additional Amounts) after such withholding or deduction will not be less than
the amount the Holder would have received if such Taxes had not been withheld or deducted; provided, however, that no Additional Amounts will be payable with respect to payments made to a Holder (an “Excluded Holder”) in respect of
a beneficial owner: 
 (1) which is subject to such Taxes by reason of its being connected with any Specified Tax
Jurisdiction otherwise than by the mere holding of Notes or the receipt of payments thereunder (or under the related Note Guarantee); 
 (2) which presents any Note for payment of principal more than 30 days after the later of (x) the date on which payment first became due and (y) if the full amount payable has not been received
by the Trustee on or prior to such due date, the date on which, the full amount payable having been so received, notice to that effect shall have been given to the Holders by the Trustee, except to the extent that the Holder would have been entitled
to such Additional Amounts on presenting such Note for payment on the last day of the applicable 30-day period; 
 (3) which failed duly and timely to comply with a reasonable, timely request of the Company to provide information, documents or other evidence concerning the Holder’s nationality, residence, entitlement to treaty benefits, identity or
connection with any Specified Tax Jurisdiction or any political subdivision or authority thereof, if and to the extent that due and timely compliance with such request would have reduced or eliminated any Taxes as to which Additional Amounts would
have otherwise been payable to such Holder but for this clause (3); 
 (4) on account of any estate, inheritance,
gift, sale, transfer, personal property or other similar Tax; 
 (5) which is a fiduciary, a partnership or not
the beneficial owner of any payment on a Note, if and to the extent that any beneficiary or settlor of such fiduciary, any partner in such partnership or the beneficial owner of such payment (as the case may be) would not have been entitled to
receive Additional Amounts with respect to such payment if such beneficiary, settlor, partner or beneficial owner had been the Holder of such Note; 
 (6) on account of Taxes imposed on a payment to an individual and required to be made pursuant to the European Union Directive on the taxation of savings, which was adopted on June 3, 2003, or any
law implementing or complying with, or introduced in order to conform to, that directive; 
 (7) to the extent
the Additional Amount relates to any Taxes imposed on a Note presented for payment by or on behalf of a Holder who would have been able to avoid that withholding or deduction by presenting the relevant Note to another Paying Agent in a member state
of the European Union; or 
 (8) any combination of the foregoing numbered clauses of this Section. 

 

 68 







 (c) The Company or any applicable Guarantor (or any successor of any of them), as
applicable, will also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority as and when required in accordance with applicable law. The Company or any applicable Guarantor (or any successor of
any of them), as applicable, will furnish to the Trustee, within 30 days after the date the payment of any Taxes is due pursuant to applicable law, copies of tax receipts evidencing such payment by the Company or such Guarantor (or any successor of
any of them), as applicable: 
 (1) in such form as provided in the normal course by the taxing authority
imposing such Taxes and as is reasonably available to the Company or such Guarantor (or any successor of any of them), as applicable; and 
 (2) certified by such taxing authority (or, if no such certification is available from such taxing authority, then by means of an Officers’ Certificate from the Company or such Guarantor (or any
successor of any of them), as applicable). 
 The Trustee shall thereafter make such evidence available to the Holders upon written request.

 (d) The Company or any Guarantor (or any successor of any of them), as applicable, will upon written request of each Holder
(other than an Excluded Holder), reimburse each such Holder for the amount of: 
 (1) any Taxes so levied or
imposed and paid by such Holder as a result of payments made under or with respect to the Notes, the Note Guarantee or a mortgaged vessel, as applicable; and 
 (2) any Taxes imposed with respect to any such reimbursement under the immediately preceding clause (1), but excluding any
Taxes on such Holder’s net income, so that the net amount received by such Holder after such reimbursement will not be less than the net amount the Holder would have received if Taxes (other than such Taxes on such Holder’s net income) on
such reimbursement had not been imposed. 
 (e) Whenever in this Indenture there is mentioned, in any context, (i) the
payment of principal, (ii) purchase or redemption prices in connection with a purchase or redemption of Notes, (iii) interest or (iv) any other amount payable on or with respect to any of the Notes, or any payment pursuant to the Note
Guarantee, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this section to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof. 
 (f) The foregoing obligations shall survive any defeasance or discharge of this Indenture. 
 (g) The Company or the Guarantor will pay any present or future stamp, court or documentary taxes or any other excise or property taxes,
charges or similar levies that arise in any jurisdiction from the execution, delivery, enforcement or registration of the Notes, the Note Guarantee or a Mortgage or other Collateral Agreement or any other document or instrument in relation thereto,
or the receipt of any payments with respect to the Notes, the Note Guarantee or a Mortgage or other Security Agreement, excluding such taxes, charges or similar levies imposed

  

 69 







 
by any jurisdiction outside of any Specified Tax Jurisdiction, the jurisdiction of incorporation of any successor of the Company or any jurisdiction in which a Paying Agent is located, and has
agreed to indemnify the Holders for any such taxes paid by such Holders.

 On the Issue Date, (1) the Parent shall advance to the Company $19.1 million in cash (the “Parent Advance”) pursuant to
an equity contribution and (2) the Company will deposit $9.1 million of such advance into an escrow account for the purpose of making the first interest payment on the Notes, which escrow account shall be established by the Noteholder
Collateral Agent, pursuant to an escrow agreement (the “Advance Escrow Agreement”) containing customary terms pursuant to which the escrowed amount shall be released directly to the Trustee and Paying Agent under this Indenture,
without requiring prior Company notice or approval, to make such first interest payment.

to a supplemental indenture or an amendment thereto, as applicable, in each case reasonable satisfactory in form to the Trustee and the Noteholder Collateral Agent, as applicable (it being agreed that if the Company merges with or into the Parent,
the Parent must assume all such obligations of the Company),

  

 72 







 
provided that, if such Person is a limited liability company or a limited partnership, then the Parent, the Company or such Person shall have the Notes assumed or issued, on a joint and
several basis, with a corporation in which it owns 100% of the Equity Interests; 
 (3) immediately after such
transaction, no Default or Event of Default exists; and 
 (4) except with respect to a transaction solely
between the Parent, the Company and/or any Guarantor, the Parent, the Company or the Person formed by or surviving any such consolidation or merger (if other than the Parent or the Company), or to which such sale, assignment, transfer, conveyance or
other disposition has been made would, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred on the first day of the applicable four-quarter period, be permitted to

 In addition, the Company will not, directly or indirectly, lease all or substantially all of the

been named as the Parent, Company or Restricted Subsidiaries herein; provided, however, that the predecessor Parent, Company or Restricted Subsidiaries shall not be relieved from the obligation to pay the principal of and interest on the
Notes except in the case of a sale of all of the Parent’s, Company’s or the applicable Restricted Subsidiaries’ assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 (“Merger,

 Each of the following is an “Event of Default”: 
 (1) default for 30 days in the payment when due of interest with respect to the Notes; 
 (2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on,
the Notes; 
 (3) failure by the Parent or the Company or any of the Restricted Subsidiaries to comply with the

subject to the following paragraph); 
 (5) default under any mortgage, indenture or instrument under which there
may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Parent, the Company or any Restricted Subsidiaries (or the payment of which is guaranteed by the Parent, the Company or any Restricted
Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, if that default: 
 (A) is caused by a failure to pay principal of, or interest or premium, if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default
(a “Payment Default”); or 
 (B) results in the acceleration of such Indebtedness prior to its
express maturity, 
 and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $10.0 million or more; 
  

 74 







 (6) failure by the Parent, the Company or any Restricted Subsidiaries to pay
final judgments entered by a court or courts of competent jurisdiction aggregating in excess of $10.0 million, which judgments are not paid, discharged or stayed for a period of 60 days after the due date thereof; 
 (7) breach by the Parent, the Company or any Restricted Subsidiary of any material representation or warranty or agreement in
the Collateral Agreements, the repudiation by the Parent, the Company or any Restricted Subsidiary of any of its obligations under the Collateral Agreements or the unenforceability of the Collateral Agreements against the Parent, the Company or any
Restricted Subsidiary for any reason; 
 (8) except as permitted by this Indenture, any Note Guarantee is held in
any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee;

 (9) the Parent, the Company or any of their Restricted Subsidiaries that is a Significant Subsidiary or any
group of their Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of Bankruptcy Law: 
 (A) commences a voluntary case; 
 (B) consents to the entry of an
order for relief against it in an involuntary case; 
 (C) consents to the appointment of a custodian of it or
for all or substantially all of its property; 
 (D) makes a general assignment for the benefit of its creditors;
or 
 (E) generally is not paying its debts as they become due; and 
 (10) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

any group of Restricted Subsidiaries of the Parent or the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case; 
 (B) appoints a custodian of the Parent, the Company or any of their Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent or the Company that,
taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Parent, the Company or any of their Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of
the Parent or the Company that, taken together, would constitute a Significant Subsidiary; or 
  

 75 







 (C) orders the liquidation of the Parent, the Company or any of their
Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Parent or the Company that, taken together, would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 
 Notwithstanding the above, if the Company elects, the sole remedy for an Event of Default relating to the failure to comply with
Section 4.17 (“Reports”), and/or for failure to comply with the requirements of Section 314(a)(1) of the TIA will, for the 60 days after the occurrence of such an Event of Default, consist exclusively of the right to receive
additional interest on the Notes at an annual rate equal to 0.25% of the principal amount of the Notes then outstanding over such portion of the 60-day period immediately following such Event of Default during which such Event of Default is
continuing (such interest, “Special Interest”). In the event the Company does not elect to pay the Special Interest, upon an Event of Default under this Section, the Notes will be subject to acceleration as provided below in
Section 6.02 (“Acceleration”). The Special Interest will accrue on all outstanding Notes from and including the date on which an Event of Default relating to a failure to comply with Section 4.17 (“Reports”) and/or for
any failure to comply with the requirements of Section 314(a)(1) of the TIA first occurs to, but not including, the 60th day thereafter (or such earlier date on which the Event of Default relating to such failure shall have been cured or
waived) and will be payable in the same manner as Special Interest. On such 60th day (or earlier, if the Event of Default relating to such failure is cured or waived prior to such 60th day) such Special Interest will cease to accrue and the Notes
will be subject to acceleration, as provided below in Section 6.02 (“Acceleration”), if the Event of Default is continuing. This provision will not affect the rights of Holders in the event of the occurrence of any other Event of
Default. 
 Notwithstanding the above, any shortfall in payment, made necessary by the existence of de minimus dollar
amounts that cannot be divided equally among the Holders shall in no way be considered a Default or Event of Default under this Indenture. 
 Section 6.02 Acceleration. 
 In the case of an Event of Default specified in clause (9) or
(10) of Section 6.01 (“Events of Default”) hereof, with respect to the Company, any Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25%
in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. 
 Section 6.03
Other Remedies. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect
the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  

 76 







 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does
not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence
in the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults.

 Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may
on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, or interest on, the Notes
(including in connection with a redemption or an offer to purchase right of Holders pursuant to Article 3); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an
acceleration and its consequences, including any related Payment Default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 
 Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability. The Trustee may also withhold from Holders of the Notes notice of any
continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest or premium. 
 Section 6.06 Limitation on Suits. 
 Subject to Section 7.01 (“Duties of Trustee”), in case an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under
this Indenture at the request or direction of any Holders unless such Holders have offered to the Trustee reasonable indemnity or security satisfactory to it against any loss, liability or expense. Except to enforce the right to receive payment of
principal, premium, if any, or interest when due, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless: 
 (1) such Holder has previously given the Trustee notice that an Event of Default is continuing; 
 (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy; 
  

 77 







 (3) such Holders have offered the Trustee reasonable security or indemnity
against any loss, liability or expense; 
 (4) the Trustee has not complied with such request within 60 days
after the receipt of the request and the offer of security or indemnity; and 
 (5) Holders of a majority in
aggregate principal amount of the then outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period. 
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 
 Section 6.07 Rights of Holders to Receive Payment. 
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates
expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder;
provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in
the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien. 
 Section 6.08
Collection Suit by Trustee or Noteholder Collateral Agent. 
 If an Event of Default specified in Section 6.01(1) or
(2) (“Events of Default”) hereof occurs and is continuing, the Trustee or the Noteholder Collateral Agent may recover judgment (a) in its own name and (b)(1) in the case of the Trustee, as Trustee of an express trust or
(2) in the case of the Noteholder Collateral Agent, as collateral agent on behalf of the Holders, in each case against the Company for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest
on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, the
Noteholder Collateral Agent and their respective agents and counsel. 
 Section 6.09 Trustee May File Proofs of Claim. 

The Trustee shall be authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to
have the claims of the Trustee or the Noteholder Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Noteholder Collateral Agent and their respective agents and counsel) and
the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other

Collateral Agent, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation,
expenses, disbursements and advances of the Trustee, the Noteholder Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee or the Noteholder Collateral Agent under the Collateral Agreements and
Section 7.07 (“Compensation and Indemnity”) hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 (“Compensation and Indemnity”) hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee or the
Noteholder Collateral Agent, as the case may be, to vote in respect of the claim of any Holder in any such proceeding.

 First: to the Trustee, the
Noteholder Collateral Agent, the Paying Agent and the Registrar for amounts due under Section 7.07 (“Compensation and Indemnity”) hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made,
by the Trustee or the Noteholder Collateral Agent, as the case may be, and the costs and expenses of collection; 
 Second: to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal,

the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This
Section does not apply to a suit by the Trustee or the

  

 79 







 
Noteholder Collateral Agent, as the case may be, a suit by a Holder of a Note pursuant to Section 6.07 (“Rights of Holders to Receive Payment”) hereof, or a suit by Holders of more

 ARTICLE 7 
 TRUSTEE 
 Section 7.01
Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the
rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default: 
 (1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 
 (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether or not
they conform to the form requirements of this Indenture. 
 (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this
paragraph does not limit the effect of paragraph (b) of this Section; 
 (2) the Trustee will not be liable
for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.05 (“Control by Majority”) hereof.

expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section. 
 (e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under
this Indenture or the Collateral Agreements at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. 
  

 80 







 (f) The Trustee will not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 
 Section 7.02 Rights of Trustee. 
 (a) The Trustee may conclusively rely
upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The
Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel
will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 
 (c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed
with due care.

 (e) Unless otherwise specifically provided
in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company. 
 (f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the
Trustee indemnity or security reasonably satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction. 
 (g) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever
(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 Section 7.03 Individual Rights of Trustee. 
 The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee
acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 (“Eligibility; Disqualification”) and 7.11 (“Preferential Collection of Claims Against Company”) hereof. 
  

 81 







 Section 7.04 Trustee’s Disclaimer. 
 The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Collateral
Agreements or the Notes, it shall not be accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible
for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the
Notes or pursuant to this Indenture other than its certificate of authentication. 
 Section 7.05 Notice of Defaults. 
 If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will mail to Holders a notice of the
Default or Event of Default within 90 days after it occurs or if discovered later than 90 days, promptly after such discovery. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or Interest on, any Note,
the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
 Section 7.06 Reports by Trustee to Holders of the Notes. 
 (a) Within 60 days after each December 15th beginning with the December 15th following the Issue Date, and for so long as Notes remain outstanding, the Trustee will mail to the Holders of the
Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).
The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit by mail all reports as required by TIA § 313(c). 
 (b) A copy of each report at the time of its mailing to the Holders will be mailed by the Trustee to the Company and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed
in accordance with TIA § 313(d). The Company will promptly notify the Trustee in writing when the Notes are listed on any stock exchange. 
 Section 7.07 Compensation and Indemnity. 
 (a) The Company will pay to the Trustee, Noteholder Collateral
Agent, Paying Agent and Registrar (each, an “Indemnified Party”) from time to time reasonable compensation for its acceptance of this Indenture, the Collateral Agreements and services hereunder and thereunder; provided that the
compensation set forth in any written fee agreement executed in connection herewith shall be deemed reasonable. The Trustee’s compensation will not be limited by any law on compensation of a Trustee of an express trust. The Company will
reimburse each Indemnified Party promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation,
disbursements and expenses of the Indemnified Party’s agents and counsel. 
  

 82 







 (b) The Company and the Guarantors will indemnify the Indemnified Party against any and all
losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture or the Collateral Agreements, including the costs and expenses of enforcing this Indenture
against the Company and the Guarantors (including this Section) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of
any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Indemnified Party will notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Indemnified Party to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder or under the Collateral Agreements. The Company or such Guarantor will defend the claim and the
Indemnified Party will cooperate in the defense. Each Indemnified Party may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel if (i) the Company shall have failed to assume the defense thereof or
employed counsel reasonably satisfactory to the Trustee, or (ii) the Trustee has been advised by such counsel that there may be one or more defenses available to it that are different from or in addition to those available to the Company.
Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. 
 (c) The obligations of the Company and the Guarantors under this Section will survive the satisfaction and discharge of this Indenture and the termination of the Collateral Agreements. 
 (d) To secure the Company’s and the Guarantors’ payment obligations in this Section, each Indemnified Party will have a Lien prior
to the Notes on all money, Collateral or property held or collected by the Trustee, in its capacity as Trustee, or the Noteholder Collateral Agent in its capacity as Noteholder Collateral Agent, except, in the case of the Trustee, that held in trust
to pay principal, premium, if any, and interest on particular Notes pursuant to Article 8 hereof. Such Lien will survive the satisfaction and discharge of this Indenture. 
 (e) When an Indemnified Party incurs expenses or renders services after an Event of Default specified in Section 6.01(9) or (10) (“Events of Default”) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable. 
 Section 7.08 Replacement of Trustee. 
 (a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section.

 (b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the
Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 (“Eligibility; Disqualification”) hereof; 
  

 83 







 (2) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law; 
 (3) a custodian or public officer
takes charge of the Trustee or its property; or 
 (4) the Trustee becomes incapable of acting. 
 (c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company will promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the
Company. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10 (“Eligibility; Disqualification”) hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 (f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders.
The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07
(“Compensation and Indemnity”) hereof. Notwithstanding replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 (“Compensation and Indemnity”) hereof will continue for the
benefit of the retiring Trustee. 
 Section 7.09 Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act will be the successor Trustee. As soon as practicable, the successor Trustee shall mail a notice of its succession to the Company and the Holders. Any such successor must nevertheless be
eligible and qualified under the provisions of Section 7.10 (“Eligibility; Disqualification”) hereof. 
  

 84 







 Section 7.10 Eligibility; Disqualification. 
 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate Trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who
satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 Section 7.11
Preferential Collection of Claims Against Company. 
 The Trustee is subject to TIA § 311(a), excluding any creditor
relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 Section 7.12 Trustee in Other Capacities; Noteholder Collateral Agent and Paying Agent. 
 References to the Trustee in Sections 7.01(b) and (f) (“Duties of Trustee”), 7.02 (“Rights of Trustee”), 7.03 (“Individual Rights of Trustee”), 7.04
(“Trustee’s Disclaimer”), 7.07 (“Compensation and Indemnity”), and 7.08 (“Replacement of Trustee”) shall be understood to include the Trustee when acting in its other capacities under this Indenture, including,
without limitation, as Paying Agent and Noteholder Collateral Agent. Without limiting the foregoing, and for the avoidance of doubt, such Sections shall be read to apply to the Noteholder Collateral Agent and the Collateral Agreements, mutatis
mutandis, in addition to this Indenture. The privileges, rights, indemnities, immunities and exculpatory provisions contained in this Indenture shall apply to the Trustee, whether it is acting under this Indenture, the other Indenture Documents
and any Intercreditor Agreement. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance
or Covenant Defeasance. 
 The Company may at any time, at the option of its Board of Directors evidenced by a resolution set
forth in an Officers’ Certificate, elect to have either Section 8.02 (“Legal Defeasance and Discharge”) or 8.03 (“Covenant Defeasance”) hereof be applied to all outstanding Notes upon compliance with the conditions set
forth below in this Article 8. 
 Section 8.02 Legal Defeasance and Discharge. 
 Upon the Company’s exercise under Section 8.01 (“Option to Effect Legal Defeasance or Covenant Defeasance”) hereof of the
option applicable to this Section 8.02 (“Legal Defeasance and Discharge”), the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 (“Conditions to Legal or
Covenant Defeasance”) hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied

  

 85 







 
(hereinafter, “Legal Defeasance”). For this purpose, “Legal Defeasance” means that the Company and the Guarantors will be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 (“Deposited Money and Government Securities to be Held
in Trust; Other Miscellaneous Provisions”) hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this
Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest
or premium, if any, on, such Notes (including in connection with any redemption or purchase of Notes pursuant to Article 3) when such payments are due from the trust referred to in Section 8.05 (“Deposited Money and Government Securities
to be Held in Trust; Other Miscellaneous Provisions”) hereof; 
 (2) the Company’s obligations with
respect to the Notes under Article 2 and Section 4.02 (“Maintenance of Office or Agency”) hereof concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or
agency for payment and money for security payments held in trust; 
 (3) the rights, powers, trusts, duties and
immunities of the Trustee, and the Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this Section and Section 8.02 (“Legal Defeasance and Discharge”) of this Indenture. 
 Subject to
compliance with this Article 8, the Company may exercise its option under this Section 8.02 (“Legal Defeasance and Discharge”) notwithstanding the prior exercise of its option under Section 8.03 (“Covenant Defeasance”)
hereof. 
 Section 8.03 Covenant Defeasance. 
 Upon the Company’s exercise under Section 8.01 (“Option to Effect Legal Defeasance or Covenant Defeasance”) hereof of the option applicable to this Section 8.03 (“Covenant
Defeasance”), the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof, be released from each of their obligations
under the covenants contained in Sections 4.07 (“Restricted Payments”), 4.08 (“Incurrence of Indebtedness and Issuance of Preferred Stock”), 4.09 (“Liens”), 4.10 (“Dividend and Other Payment Restrictions Affecting
Subsidiaries”), 4.11 (“Transactions with Affiliates”), 4.12 (“Business Activities”), 4.13 (“Credit Rating for the Notes”), 4.14 (“Additional Note Guarantees”), 4.15 (“Designation of Restricted and
Unrestricted Subsidiaries”), 4.16 (“Payments for Consent”), 4.17 (“Reports”), 4.18 (“Offer to Repurchase Upon Change of Control”) and 4.19 (“Asset Sales”), 4.20 (“Impairment of Security
Interest”), 4.12 (“Withholding Taxes”), 4.22 (“Parent Advance”), 4.23 (“Topaz Driller Delivery Date”) and

  

 86 







 
4.24 (“Post-Topaz Driller Delivery Date”) hereof and clause (4) of Section 5.01 (“Merger, Consolidation or Sale of Assets”) and Article 12 hereof with respect to the
outstanding Notes on and after the date the conditions set forth in Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will thereafter be
deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding”
for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other
document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 (“Events of Default”) hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note
Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 (“Option to Effect Legal Defeasance or Covenant Defeasance”) hereof of the option applicable to this Section 8.03
(“Covenant Defeasance”), subject to the satisfaction of the conditions set forth in Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof, Sections 6.01(3) through 6.01(8) (“Events of Default”) hereof
will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 (“Legal Defeasance and
Discharge”) or 8.03 (“Covenant Defeasance”) hereof: 
 (1) the Company must irrevocably deposit
with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in
the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants, to pay the principal of, or interest and premium on, the outstanding Notes on the stated date for payment thereof or on the applicable
Redemption Date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular Redemption Date; 
 (2) in the case of Legal Defeasance, the Company must deliver to the Trustee an Opinion of Counsel confirming that
(a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel will confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  

 87 







 (3) in the case of Covenant Defeasance, the Company must deliver to the
Trustee an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit)
and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under,
any material agreement or instrument (other than this Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited
Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06
(“Repayment to Company”) hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying Trustee, collectively for purposes of this Section, the “Trustee”)
pursuant to Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof in respect of the outstanding Notes will be held (i) held in trust, (ii) at the written direction of the Company, such money may be invested,
prior to maturity of the Notes, in Government Securities, and (iii) applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the
extent required by law. 
 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof or the principal and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
  

 88 







 Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay
to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 (“Conditions to Legal or Covenant Defeasance”) hereof which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) (“Conditions to Legal or Covenant
Defeasance”) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
 Section 8.06 Repayment to Company. 
 Subject to any unclaimed property
law, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal, premium,
if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Company for
payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or Government Securities, and all liability of the Company as Trustee thereof, will thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times or The Wall Street Journal, notice that such money remains unclaimed and that, after a date specified
therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable
to apply any U.S. dollars or non-callable Government Securities in accordance with Sections 8.02 (“Legal Defeasance and Discharge”) or 8.03 (“Covenant Defeasance”) hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived and
reinstated as though no deposit had occurred pursuant to Section 8.02 (“Legal Defeasance and Discharge”) or 8.03 (“Covenant Defeasance”) hereof until such time as the Trustee or Paying Agent is permitted to apply all such
money in accordance with Section 8.02 (“Legal Defeasance and Discharge”) or 8.03 (“Covenant Defeasance”) hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium,
if any, or interest on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying
Agent.

 Section 9.01 Without Consent of Holders.

 Notwithstanding Section 9.02 (“With Consent of Holders”) of this Indenture, the Company, the Guarantors and the
Trustee and, if any amendment or supplement relates to any Collateral Agreement, the Noteholder Collateral Agent, may amend or supplement this Indenture, the Notes, the Collateral Agreements, the Note Guarantees or the Intercreditor Agreement (if
any) without the consent of any Holder of Note: 
 (1) to cure any ambiguity, defect or inconsistency;

 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable;

 (6) to conform the text of this Indenture, the Collateral Agreements, the Notes or the Note Guarantees to any

Guarantees, which intent shall be evidenced by an Officers’ Certificate to that effect; 
 (7) to evidence
and provide for the acceptance of the appointment under this Indenture and the Collateral Agreements of a successor Trustee or Noteholder Collateral Agent; 
 (8) to make any other provisions with respect to matters or questions arising under this Indenture, the Collateral Agreements, the Notes, the Note Guarantees or the Intercreditor Agreement (if any),

 (9) to enter into additional or supplemental Collateral Agreements; 
 (10) to release Collateral when permitted or required by this Indenture or the Collateral Agreements;

 (14) to accept and consent to, and to take all steps to perfect a security interest under, Collateral Agreements to be
granted subsequent to the Issue Date respecting Drilling Contracts and Internal Charters and insurances covering the Topaz Driller. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the
documents described in Section 7.02(b) (“Rights of Trustee”) hereof, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this
Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities
under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders. 
 Except as provided in Section 9.01 (“Without Consent of Holders”) and in this Section, this Indenture, the Notes, the
Collateral Agreements, the Note Guarantees or the Intercreditor Agreement (if any) may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes, the Collateral Agreements or
the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or
exchange offer for, Notes). Sections 2.08 (“Outstanding Notes”) and Section 2.09 (“Treasury Notes”) hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section.

 Without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a
non-consenting Holder): 
 (1) reduce the principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver; 
 (2) reduce the principal of or change the fixed maturity of any Note or alter the
provisions with respect to the purchase or redemption of the Notes (other than provisions relating to the covenants described above under Sections 3.07 (“Optional Redemption”), 3.08 (“Optional Redemption for Changes in Withholding
Taxes”), Section 3.09 (“Special Mandatory Redemption”), 4.18 (“Offer to Repurchase Upon a Change of Control”) and 4.19 (“Asset Sales”)); 
  

 91 







 (3) reduce the rate of or change the time for payment of interest on any
Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or interest, premium, if any, on
the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a waiver of the Payment Default that resulted from such acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to
receive payments of principal of, or interest on the Notes; 
 (7) waive a redemption or repurchase payment with
respect to any Note (other than a payment required by one of the covenants described above under Sections 3.07 (“Optional Redemption”), 3.08 (“Optional Redemption for Changes in Withholding Taxes”), Section 3.09
(“Special Mandatory Redemption”), 4.18 (“Offer to Repurchase Upon a Change of Control”) and 4.19 (“Asset Sales”)); 
 (8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; 
 (9) release all or substantially all of the Collateral, including from Liens created pursuant to the Collateral Agreements,
otherwise than in accordance with this Indenture and the Collateral Agreements; or 
 (10) make any change in the
preceding amendment and waiver provisions. 
 Section 9.03 Compliance with TIA. 
 Every amendment or supplement to this Indenture or the Notes will be set forth in an amended or supplemental indenture that complies with the
TIA as then in effect. 
 Section 9.04 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms
and thereafter binds every Holder. 
 The Company may, but shall not be obligated to, fix a Record Date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or waiver. If a Record Date is fixed, then notwithstanding the immediately preceding paragraph, those Persons

  

 92 







 
who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously
given, whether or not such Persons continue to be Holders after such Record Date. 
 Section 9.05 Notation on or Exchange of Notes.

 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated.
The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or
waiver. 
 Section 9.06 Trustee and Noteholder Collateral Agent to Sign Amendments, etc. 
 The Trustee and/or the Noteholder Collateral Agent will sign any amended or supplemental indenture authorized pursuant to this Article 9 if
the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee and/or the Noteholder Collateral Agent. The Company may not sign an amended or supplemental indenture until the Board of Directors of
the Company approves it. In executing any amended or supplemental indenture, the Trustee and/or the Noteholder Collateral Agent, as the case may be, will be entitled to receive and (subject to Section 7.01 (“Duties of Trustee”)
hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.04 (“Certificate and Opinion as to Conditions Precedent”) hereof, an Officers’ Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 
 ARTICLE 10

 SATISFACTION AND DISCHARGE 
 Section 10.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of
further effect as to all Notes issued thereunder when: 
 (1) either: 
 (A) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes
for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or 
 (B) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within
one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in

  

 93 







 
U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, without consideration of any
reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium and accrued interest to the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of the deposit (other than a Default or Event
of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by
which the Company or any Guarantor is bound; 
 (3) the Company or any Guarantor has paid or caused to be paid
all sums payable by it under this Indenture; and 
 (4) the Company has delivered irrevocable instructions to the
Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the Redemption Date, as the case may be. 
 In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause
(B) of clause (1) of this Section, the provisions of Sections 10.02 (“Application of Trust Money”) and 8.06 (“Repayment to Company”) hereof will survive. In addition, nothing in this Section will be deemed to discharge
those provisions of Section 7.07 (“Compensation and Indemnity”) hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 
 Section 10.02 Application of Trust Money. 
 Subject to the provisions
of Section 8.05 (“Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions”) hereof, all money deposited with the Trustee pursuant to Section 10.01 (“Satisfaction and Discharge”)
hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by
law. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with
Section 10.01 (“Satisfaction and Discharge”) hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.01 (“Satisfaction and Discharge”) hereof;

  

 94 







 
provided that if the Company has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to
the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. 
 ARTICLE 11 
 GUARANTEES 
 Section 11.01 Guarantee. 
 (a) Subject to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees on a senior secured basis to the extent, with respect to security, set forth in Article 12 and the Collateral Agreements, to
each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and the Noteholder Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes, the
Collateral Agreements or the obligations of the Company hereunder or thereunder, that: 
 (1) the principal of,
premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the
Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee and the Noteholder Collateral Agent hereunder or thereunder or under any Collateral Agreement will be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and 
 (2) in case of any extension of time of payment or renewal
of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly
and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes, any Collateral Agreement or this Indenture, the
absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company,
any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this
Indenture. 
  

 95 







 (c) If any Holder, the Noteholder Collateral Agent or the Trustee is required by any court
or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee, the Noteholder Collateral
Agent or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further
agrees that, as between the Guarantors, on the one hand, and the Holders, the Noteholder Collateral Agent and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6
hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of
such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 
 Section 11.02 Limitation on Guarantor Liability. 
 Each Guarantor, and by its acceptance of Notes, each
Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such
Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of each such Guarantor that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 11, result in the obligations of such Guarantor under its Note Guarantee not
constituting a fraudulent transfer or conveyance. 
 Section 11.03 Execution and Delivery of Guarantee. 
 To evidence its Note Guarantee set forth in Section 11.01 (“Guarantee”) hereof, each Guarantor hereby agrees that a notation
of such Note Guarantee substantially in the form attached as Exhibit E hereto will be signed by an Officer of such Guarantor (by manual or facsimile signature) on each Note authenticated and delivered by the Trustee and that this Indenture will be
executed on behalf of such Guarantor by one of its Officers. 
 Each Guarantor hereby agrees that its Note Guarantee set forth
in Section 11.01 (“Guarantee”) hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
  

 96 







 If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds
that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. 

In the event that the Company or any of its Restricted Subsidiaries creates or acquires any Subsidiary after the Issue Date, if required
by Section 4.14 (“Additional Note Guarantees”) hereof, the Company will cause such Subsidiary to comply with the provisions of Section 4.14 (“Additional Note Guarantees”) hereof and this Article 11, to the extent
applicable. 
 Section 11.04 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in Section 11.05 (“Releases”) hereof, no Guarantor may sell or otherwise dispose of all or
substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 
 (1) immediately after giving effect to that transaction, no Default or Event of Default exists; and 
 (2) either: 
 (A) subject to Section 11.05 (“Releases”) hereof, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger
assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee and the Collateral Agreements pursuant to a supplemental indenture reasonably satisfactory in form to the Trustee; or 
 (B) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this
Indenture and the Collateral Agreements. 
 provided, however, that the transfer, sale or other disposition, directly or indirectly, of
all or substantially all of the assets of, directly or indirectly, the Guarantors as a whole will be governed by Article 5 and Section 4.19 (“Asset Sales”) and may be subject to Section 4.18 (“Offer to Repurchase Upon Change
of Control”). 
 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor
Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or
all of the Note Guarantees to be endorsed upon

  

 97 







 
all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same
legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

 Section 11.05 Releases. 
 The Note Guarantee of a Guarantor will be released: 
 (1) in
connection with any transfer, sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the
Company, a Guarantor or a Restricted Subsidiary, if the sale or other disposition does not violate Section 4.19 (“Asset Sales”) or Article 5 of this Indenture and complies with the Collateral Agreements; 
 (2) in connection with any transfer, sale or other disposition of all of the Capital Stock of that Guarantor to a Person that
is not (either before or after giving effect to such transaction) the Company, a Guarantor or a Restricted Subsidiary, if the transfer, sale or other disposition does not violate Section 4.19 (“Asset Sales”) or Article 5 of this
Indenture and complies with the Collateral Agreements; 
 (3) if the Parent or Company designates any Restricted
Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or 
 (4) upon Legal Defeasance or satisfaction and discharge of this Indenture as provided under Sections 8.02 (“Legal Defeasance and Discharge”), 8.03 (“Covenant Defeasance”) and 10.01
(“Satisfaction and Discharge”). 
 Any Guarantor not released from its obligations under its Note Guarantee as
provided in this Section will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11. 
 ARTICLE 12 
 SECURITY

 Section 12.01 Grant of Security Interests; Intercreditor Agreement. 
 (a) The Company and the Guarantors: 
 (1) shall grant a security interest in the Collateral as set forth in the Collateral Agreements to the Noteholder Collateral Agent for the benefit of the Holders and the Trustee, to secure the due and
punctual payment of the principal of, premium, if any, and interest on the Notes and amounts due hereunder and under the Note Guarantees when and as the same shall be due and payable, whether at Stated Maturity thereof, on an

subject to the terms of any Intercreditor Agreement and any other Permitted Liens; 
 (2) hereby covenant
(A) to perform and observe their obligations under the Collateral Agreements and (B) take any and all commercially reasonable actions (including without limitation the covenants set forth in Section 4.20 (“Impairment of Security
Interest”), Section 4.23 (“Topaz Driller Delivery Date”) and Section 4.24 (“Post-Topaz Driller Delivery Date”) and in this Article) required to cause the Collateral Agreements to create and maintain,
as security for the Obligations contained in this Indenture, the Notes, the Collateral Agreements and the Note Guarantees valid and enforceable, perfected (except as expressly provided herein or therein) security interests in and on all the
Collateral, in favor of the Noteholder Collateral Agent, superior to and prior to the rights of all third Persons, and subject to no other Liens (other than Permitted Liens), in each case, except as expressly permitted herein, therein or in any
Intercreditor Agreement; 
 (3) shall warrant and defend the title to the Collateral against the claims of all
persons, subject to any Intercreditor Agreement and any Permitted Liens; and 
 (4) shall do or cause to be done,
at their sole cost and expense, all such actions and things as may be necessary, or as may be required by the provisions of the Collateral Agreements, to confirm to the Noteholder Collateral Agent the security interests in the Collateral
contemplated hereby and by the Collateral Agreements, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes and Note Guarantees secured hereby, according to the intent
and purpose herein and therein expressed. 
 (b) Each Holder, by its acceptance of a Note: 
 (1) appoints the Noteholder Collateral Agent to act as its agent (and by its signature below, the Noteholder Collateral Agent
accepts such appointment); 
 (2) consents and agrees to the terms of each Collateral Agreement, as the same may
be in effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms, and authorizes and directs the Noteholder Collateral Agent to enter into the Collateral Agreements and to
perform its obligations and exercise its rights thereunder in accordance therewith; and 
 (3) appoints and
authorizes the Noteholder Collateral Agent and the Trustee to enter, at a future date, into an Intercreditor Agreement with an LC Collateral Agent; or 
 (4) any bank or financial institution that intends to provide, or is in fact providing, an LC Facility to the Company or any Guarantor. 
  

 99 







 (c) This Article 12, the Security Agreement and the other Collateral Agreements (other than
any Intercreditor Agreement) will be subject to the terms, limitations and conditions set forth in any Intercreditor Agreement. 
 (d) The Trustee will determine the circumstances and manner in which the Collateral will be disposed of, including, but not limited to, the determination of whether to release all or any portion of the Collateral from the Liens created by
the Collateral Agreements and whether to foreclose on the Collateral following a Default or Event of Default. 
 Section 12.02 Recording
and Opinions. 
 (a) The Company shall, and shall cause each of the Guarantors to, at their sole cost and expense, take or
cause to be taken all commercially reasonable action required to perfect (except as expressly provided in the Collateral Agreements), maintain (with the priority required under the Collateral Agreements), preserve and protect the security interests
in the Collateral granted by the Collateral Agreements, including (i) the filing of financing statements, continuation statements, collateral assignments and any instruments of further assurance, in such manner and in such places as may be
required by law to preserve and protect fully the rights of the Holders, the Noteholder Collateral Agent, and the Trustee under this Indenture and the Collateral Agreements to all property comprising the Collateral pursuant to the terms of the
Collateral Agreements, and (ii) the delivery of the certificates, if any, evidencing the certificated securities pledged under the Collateral Agreements, duly endorsed in blank or accompanied by undated stock powers or other instruments of
transfer executed in blank. The Company shall from time to time promptly pay all financing and continuation statement recording and/or filing fees, charges and recording and similar taxes relating to this Indenture, the Collateral Agreements and any
amendments hereto or thereto and any other instruments of further assurance required pursuant thereto. Neither the Company nor any Guarantor will be permitted to take any action, or omit to take any action, which action or omission might or would
have the result of materially impairing the security interest with respect to the Collateral for the benefit of the Notes Collateral Agent, the Trustee or the Holders except as expressly set forth herein, in any Intercreditor Agreement or the
Collateral Agreements. 
 (b) If property of a type constituting Collateral is acquired by the Company or any Guarantor that is
not automatically subject to a Lien or perfected security interest under the Collateral Agreements or there is a new Guarantor, then the Company or such Guarantor will, as soon as practicable after such property’s acquisition or such Subsidiary
becoming a Guarantor and in any event within 10 Business Days, grant Liens on such property (or, in the case of a new Guarantor, all of its assets constituting the type that is Collateral) in favor of the Noteholder Collateral Agent and deliver
certain certificates (including in the case of real property title insurance) in respect thereof as required by this Indenture or the Collateral Agreements and take all necessary steps to perfect the security interest represented by such Liens.

 (c) The Company shall furnish to the Trustee and the Collateral Agent (if other than the Trustee), on or within one month of
December 31 of each year, commencing December 31, 2009, an Opinion of Counsel either (1) stating that, in the opinion of such counsel, all action necessary to perfect or continue the perfection of the security interests created by the
Collateral Agreements and reciting the details of such action or referring to prior Opinions of Counsel in

  

 100 







 
which such details are given have been taken or (2) stating that, in the Opinion of such Counsel, no such action is necessary to perfect or continue the perfection of any security interest
created under any of the Collateral Agreements. 
 Section 12.03 Release of Collateral. 
 (a) The Company and the Guarantors will be entitled to releases of assets included in the Collateral from the Liens securing Obligations

 (1) upon the full and final payment
and performance of all Obligations of the Company and the Guarantor under the Notes, this Indenture, the Note Guarantee and the Collateral Agreements; 
 (2) with respect to any asset constituting Collateral (other than the Capital Stock of the Company), if such Collateral is sold or otherwise disposed of in accordance with the terms of Section 4.19
(“Asset Sales”) and the Collateral Agreements and the Company has delivered to the Noteholder Collateral Agent an Officers’ Certificate certifying to such effect; provided that (a) any cash received from a disposition of
Collateral will be required to be deposited in a deposit account controlled by the Company and held as Collateral subject to the Liens pending its application or use in compliance with Section 4.19 (“Asset Sales”) and, from such
deposit account, the Parent, the Company or any Restricted Subsidiary may withdraw funds to deploy the proceeds of an Asset Sale in compliance with Section 4.19 (“Asset Sales”); and (b) to the extent that any disposition in such
Asset Sale was of Collateral, the non-cash consideration received is pledged as Collateral under the Collateral Agreements substantially simultaneously with such sale, in accordance with the requirements set forth in this Indenture and the
Collateral Agreements; 
 (3) upon legal or covenant defeasance or satisfaction and discharge of the Notes as
provided in Sections 8.02, 8.03 and 10.01 (“Legal Defeasance and Discharge,” “Covenant Defeasance” and “Satisfaction and Discharge,” respectively); 
 (4) with respect to an applicable Subsidiary, upon the occurrence of a Contract Unwind Trigger; or 
 (5) if any Guarantor is released from its Note Guarantee in accordance with the terms of this Indenture (including by virtue
of such Guarantor ceasing to be a Restricted Subsidiary), that Guarantor’s assets will also be released from the Liens securing its Note Guarantee and the other Obligations. 
 (b) In addition to the foregoing, the Company and the Guarantor will comply with the provisions of TIA Section 314. To the extent
applicable, the Company and the Guarantor will comply with TIA Section 313(b), relating to reports, and TIA Section 314(d), relating to the release of property or securities or relating to the substitution therefore of any property or
securities to be subjected to the Lien of the security documents. Any certificate or opinion required by TIA Section 314(d) may be made by an Officer of the Parent or the Company except in cases where TIA Section 314(d) requires that such
certificate or opinion be made by an

  

 101 







 
independent Person, which Person will be an independent engineer, appraiser or other expert. Notwithstanding anything to the contrary in this paragraph, neither the Parent nor the Company will be
required to comply with all or any portion of TIA Section 314(d) if it determines, in good faith based on advice of counsel, that under the terms of TIA Section 314(d) and/or any interpretation or guidance as to the meaning thereof of the
SEC, including “no action” letters or exemptive orders, all or any portion of TIA Section 314(d) is inapplicable to one or a series of released Collateral. 
 (c) Upon receipt of any necessary or proper instruments of termination, satisfaction or release prepared by the Company or the Guarantors, as the case may be, the Noteholder Collateral Agent shall
execute, deliver or acknowledge such instruments or releases to evidence the release of any Collateral permitted to be released pursuant to this Indenture or the Collateral Agreements, including the Intercreditor Agreement. 
 (d) The release of any Collateral from the terms of the Collateral Agreements shall not be deemed to impair the security under this
Indenture in contravention of the provisions hereof if and to the extent the Collateral is released pursuant to this Indenture and the Collateral Agreements. 
 Section 12.04 Form and Sufficiency of Release. 
 In the event that the
Company or any Guarantor has sold, exchanged, or otherwise disposed of or proposes to sell, exchange or otherwise dispose of any portion of the Collateral that may be sold, exchanged or otherwise disposed of by the Company or any Guarantor to any
Person other than the Company or a Guarantor, and the Company or any Guarantor requests in writing that the Noteholder Collateral Agent furnish a written disclaimer, release or quit-claim of any interest in such property under this Indenture and the
Collateral Agreements, the Noteholder Collateral Agent shall execute, acknowledge and deliver to the Company or such Guarantor (in proper form prepared by the Company or such Guarantor) such an instrument promptly after satisfaction of the
conditions set forth herein for delivery of any such release. Notwithstanding the preceding sentence, all purchasers and grantees of any property or rights purporting to be released herefrom shall be entitled to rely upon any release executed by the
Noteholder Collateral Agent hereunder as sufficient for the purpose of this Indenture and as constituting a good and valid release of the property therein described from the Lien of this Indenture or of the Collateral Agreements. 
 Section 12.05 Authorization of Actions to be Taken by the Noteholder Collateral Agent Under the Collateral Agreements. 
 Subject to the provisions of the applicable Collateral Agreements, the Trustee and each Holder, by acceptance of any Notes agrees that
(a) the Noteholder Collateral Agent shall execute and deliver the Collateral Agreements, and all agreements, documents and instruments incidental thereto, and act in accordance with the terms thereof, (b) the Noteholder Collateral Agent
may, in its sole discretion and without the consent of the Trustee or the Holders, take all actions it deems necessary or appropriate in order to (i) enforce any of the terms of the Collateral Agreements and (ii) collect and receive any
and all amounts payable in respect of the Obligations of the Company and the Guarantors hereunder and under the Notes, the Note Guarantees and the Collateral

Agreements and (c) the Noteholder Collateral Agent shall have power to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the
Collateral by any act that may be unlawful or in violation of the Collateral Agreements or this Indenture, and suits and proceedings as the Noteholder Collateral Agent may deem expedient to preserve or protect its interests and the interests of the
Trustee and the Holders in the Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be
unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest thereunder or be prejudicial to the interests of the Noteholder Collateral Agent, the Holders or the
Trustee). Notwithstanding the foregoing, the Noteholder Collateral Agent may, at the expense of the Company, request the direction of the Holders with respect to any such actions and upon receipt of the written consent of the Holders of at least a
majority in aggregate principal amount of the then outstanding Notes, shall take such actions; provided that all actions so taken shall, at all times, be in conformity with the requirements of any future Intercreditor Agreement, if applicable.

 Section 12.06 Authorization of Receipt of Funds by the Trustee Under the Collateral Agreements. 
 The Noteholder Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed under
the Collateral Agreements and to the extent not prohibited under any future Intercreditor Agreement, as applicable, for turnover to the Trustee to make further distributions of such funds to itself, the Trustee and the Holders in accordance with the
provisions of Section 6.10 (“Priorities”) and the other provisions of this Indenture.

Noteholder Collateral Agent. 
 A resignation or removal of the Noteholder Collateral Agent and appointment of a successor
Noteholder Collateral Agent may be effected pursuant to the terms of the Security Agreement.

Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than as permitted or required to by this Indenture, the Collateral Agreements or any Intercreditor Agreement. 
 (b) To the extent that any instrument, Mortgage or other document is required to be delivered to give effect to and perfect the Liens
(including with respect to the Topaz Driller when title thereto becomes legally vested in the Company), the Company and the Guarantors will be required to use their commercially reasonable efforts to deliver such instruments, Mortgages and/or
other documents as soon as possible but in no event later than 10 Business Days following the Issue Date or, if an asset is acquired or delivered after the Issue Date, not later than 10 Business Days after such acquisition or delivery date. Upon the
occurrence of a Contract Winning Trigger, the Parent or the Company shall cause the applicable Subsidiary to

  

 103 







 
pledge its assets and property pursuant to the Collateral Agreements to become part of the Collateral subject to the Liens and shall perfect such Liens as soon as practicable but not later than
10 Business Days after the date of such Contract Winning Trigger; and such Liens shall be released upon the occurrence of a Contract Unwind Trigger, provided that no assets or property have been transferred or sold, directly or indirectly, by the
Company or a Guarantor to such applicable Subsidiary that is subject to Section 4.19 (“Asset Sales”). 
 (c) The
Parent and the Company shall, and they shall cause any Guarantor to, at their sole cost and expense, (i) execute and deliver all such agreements and instruments and take all further action as the Noteholder Collateral Agent or the Trustee shall
reasonably request to more fully or accurately describe the property intended to be Collateral or the obligations intended to be secured by the Collateral Agreements; and (ii) file any such notice filings or other agreements or instruments as
may be reasonably necessary under applicable law to perfect the Liens created by the Collateral Agreements.
